Are you talking about this topic or are you asking about the movie with the cars called Transformers
A transformer breather is an acessory of an oil filled type transformer which is attached into the oil conservator tank; this serves as the breathing point of the unit, that when the insulating oil of the transformer gets heated up, it expands and goes back to the conservator tank and subsequently pushes the dry air out of the conservator tank through the breather which is filled with silica gel, when the oil cools down, it retracts and sucks fresh air from the athmosphere through the breather and from this point, the silica gel dries up the air that goes back in to the conservator tank. for a better understanding have a look at the following pic: http://www.csanyigroup.com/wp-content/uploads/posts/transformer-oil-diagnostics/img-1.jpg

It is expensive to repair
because they decompose easily giving out toxic gases.............AnswerThey are cancer-causing.
Metal gets oxidized.
Yy is a heterozygous genotype. Homozygous would be YY or yy.
Takes quiet a bit of time to produce.
yY
As of July 2014, the market cap for YY Inc. (YY) is $4,131,123,992.20.
The symbol for YY Inc. in NASDAQ is: YY.
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
When crossing two heterozygous pea plants (Yy x Yy) using a Punnett square, the resulting genotypes are YY, Yy, Yy, and yy. This results in a 1:2:1 genotype ratio, where 25% of the offspring will be homozygous dominant (YY), 50% will be heterozygous (Yy), and 25% will be homozygous recessive (yy). The phenotypic ratio will be 3 yellow (YY and Yy) to 1 green (yy).
cannot be used as an isolating transformer, because is has common winding.
In a Yy x Yy cross, where "Y" represents a dominant trait and "y" represents a recessive trait, you can expect a phenotypic ratio of 3:1 among the offspring. This means that approximately 75% of the plants would display the dominant trait (YY or Yy), while about 25% would display the recessive trait (yy). The genotypic ratio would be 1 YY : 2 Yy : 1 yy.
Disadvantages of power transformers depend on the type of transformer. Some disadvantages to three phase power transformers include greater cost of standby units and issues with repairs should one phase fail or be damaged.
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
The genotype of the offspring with yellow pods is likely homozygous dominant (YY) or heterozygous (Yy), assuming yellow pods are dominant over green. The possible genotypes of the offspring with green pods would be homozygous recessive (yy), as green is the recessive trait. If both yellow-podded parents are heterozygous (Yy), some offspring could also be yellow (YY or Yy) while others could be green (yy).
